Site Selection and Soil Preparation
Sunlight:
- Sweet peas need at least 6 hours of sunlight daily. In hotter regions, provide afternoon shade to protect them from scorching.
Soil:
- They prefer well-draining, fertile soil with a slightly alkaline pH (6.5–7.5). Enrich the soil with compost or well-rotted manure before planting.
Drainage:
- Ensure the soil is not waterlogged, as sweet peas dislike wet feet.
How to Plant Sweet Peas
Seeds:
- Soak seeds in water for 24 hours before planting to improve germination.
- Sow seeds directly into the garden or start them in seed trays.
- Plant seeds 12 mm deep, spacing them 8 cm apart.
- If using seed trays, transplant seedlings when they are 5–7 cm tall.
Support:
Bush varieties:
- Small 1 m canes can be used to provide support, or they can be allowed to tumble for a softer effect.
Climbing varieties:
- Trellising needs to be set up for support
Watering and Feeding
Watering:
- Keep the soil consistently moist but not waterlogged.
- Water deeply once or twice a week, depending on rainfall and temperature.
Feeding:
- Sweet peas are heavy feeders.
- Apply a balanced liquid fertiliser every 2–3 weeks during the growing season.
- Alternatively, use a slow-release fertiliser at planting time.
Mulching and Weeding
- Apply a layer of mulch (e.g., straw or sugar cane mulch) around the plants to retain moisture and suppress weeds.
- Keep the area weed free to reduce competition for nutrients.
Pest and Disease Management
Sweet peas are relatively pest resistant but can be affected by:
Aphids:
- Spray with a mild soap solution or use neem oil.
Powdery Mildew:
- Ensure good air circulation and avoid overhead watering. Treat with a fungicide if necessary.
Snails and Slugs:
- Use organic bait or traps to protect young plants.
Pruning and Deadheading
Pinching:
- Pinch out the growing tip when seedlings are 10–15 cm tall to encourage bushier growth.
Deadheading:
- Remove spent flowers regularly to promote continuous blooming.
Cutting Flowers:
- Harvest flowers frequently for bouquets to encourage more blooms.
Saving Seeds
- Allow some pods to mature and dry on the plant.
- Harvest the pods when they turn brown and brittle.
- Remove the seeds and store them in a cool, dry place for planting next season.
Common Problems and Solutions
Poor Germination:
- Ensure seeds are soaked before planting and soil is kept moist.
Yellowing Leaves:
- Often a sign of overwatering or nutrient deficiency.
- Check drainage and fertilise if needed.
Lack of Flowers:
- This can be due to insufficient sunlight, poor soil fertility, or excessive nitrogen.
- Address these issues to encourage blooming.
Sweet Peas in Pots
- Sweet peas can be grown in pots if space is limited:
- Choose a deep pot (at least 30 cm deep) with good drainage.
- Use a high-quality potting mix enriched with compost.
- Provide a trellis or support for climbing.
- Water and feed regularly, as potted plants dry out faster.
- Companion Planting
Sweet peas grow well with:
Roses:
- Their climbing habit complements rose bushes.
Lettuce and Spinach:
- Sweet peas provide shade for these cool season crops.
Avoid planting with:
- Onions or garlic, as they can inhibit growth.
